This is a plugin for Rails that performs automatic text-to-html formatting.

For rails 2.3, please use the 'rails23' branch (you can specify ~> 0.2 in your gemfile)

It uses the 'redcarpet' markdown library with a few other pre-processing steps. Note: tests do not run on 1.9.x series due to a bug in the test frameworks we use, but the code works fine.

It is extracted from and used by [Tender]( and [Lighthouse](
